'My invention relates to plumbing fixtures; and has among its objects and advantages the pro- 'vision of an improved floor drain. The invention embodies means actuated by the reverse flow of drainage for preventing` such drainage from escaping from the floor drain. t i

This invention also consists in certain other features of construction and-in the combination and arrangement of the several parts to be hereo inafter fully described, illustrated in the accompanying drawing, and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawing s wherein like characters denote like or corresponding parts throughout the several views,` and in which: v Fig. 1 is a top plan view; 4 `Fig. 2 is a fragmentary sectional view taken along the line 2-2 of Fig. 1;

Fig. 3 is a sectional View along line 3-3 of Fig. 2, and

Fig. 4 is a diagrammatic sectional view of a different form. In the embodiment selected to illustrate my invention, I make use of a sectionof tile 10 comprising a part of the usual drain pipe associated with a floor indicated generally at. 12 having its upper surface in'dicated at`14. The tiletis usually made in twenty-four inch lengths with an inside diameter of approximately four inchesl Within the tile section 10, I position' a tubular section 16 having its outer wall fitting snugly within the tile.

Around the upper end of the tubular section 16,

I fasten a ring 18 having threaded relation with.,

the section 16 at 20 and provided with an integral flange 22 extending inwardly of the section and an integral flange 24 arranged to lie within the enlarged portion 26 of the tile 10 and embedded in the cement of the floor 12. A scaling ring 28 may be positioned between the upper end of the' of the tube, in addition to permitting the necessary movement of air into and out of the space between the tubes 16 and 30.

In Fig. 2, the upper end of the tube 30 has threaded relation with a depending flange 36 formed integrally with a plate 38 having its upper face terminating flush with the floor line 14.

Nornally the plate 36 rests upon the flange 22. Threads 40 are cut in the inner Wall of the flange F 36 for receiving the threaded end of a short tube 42 having a fiange 44 screwed into its lower end. A sealing ring 46 may be positioned between the upper end of the tube 42 and the plate 38 and a similar ring 48 may be positioned between the upper end of the tube 30 and the plate.

I mo-unt a perforated disc 50 within a groove 52 cut in the upper face of the plate 38 to permit drainage to flow into the tube 42and the drain pipe. Referring to Fig. 2, a fourth tube 54 is movably guided by the flange 44 and carries a fiange 56 arranged to rest on the fiange 44 to support the tube in the normal position illustrated. The lower end of the tube 54 is enlargedat 58 and is provided with a closure plate 60 cooperating with the enlarged portion'to provide a fioat 62. A plurality of semi-circular openings 64 in the tube 54 below thefiange 44 permits drainage entering the tube to flow into the drain pipe around the fioat. -I make the openings 64 semicircular to give them width and short vertical dimensions; thus decreasing the necessary length of the tube 54 while giving the tube the necessary fluid outlet Capacity. 4

In operation, the float 62 is normally positioned as indicated in Fig. 2. However, should backwater rise in the tube 30 to a level sufficient to lift thefioat '62, the communication between the tube 54 and the tube 30-is cut off as soon as the tube 54 has been lifted sufficiently far to position the openings 64 beyond the lower end of the flange 44. This Construction makes the tube 54 and the flange 44 operate as a valve. Thus drainage in the nature of backwater is efiectively prevented from flooding the floor 12.

Continued upward movement of the tube 54 brings its upper end into engagement with" a rubber scaling ring 66 lying against the plate 33. Further increase in the level of the backwater will lift the tube 30 through the medium of the plate 38. In this way my telescopic arrangenient of the tube sections prevents the backwater from engaging a fixed abutment, thereby eliminating the danger of breakage due to back pressure.

A further important feature resides in the arrangement of the parts to permit elevation thereof to a level above the floor line to indicate a backwater condition in the drain pipe.

The disc 50 is made removable to permit access to the tube 54 should it become necessary to remove any accumu'lation of waste material which might close the openings 64 or load the fioat 62.

In installations where it is necessary to accommodate backwater of relatively high level it may be necessary to incorporate more than the one tube 30 illustrated in Figs. 2 and 4. To this end I illustrate in Fig. 4 a construction in which an additional tube 67 is positioned between the tubes 68 and 70 corresponding to the tubes 16 and 30, respeotively, `in Fig. 2 Obyiously any number of tubes may be incorporated in annit.

Without further elaboration, the foregoing will so fully explain my invention that others may, by applying current knowledge, readily adapt the same for use under various conditions ;of service.
